1720 B-Staley Mod

I went to do the B-Staley o-ring mod to my new 1720, but when I went to take out the hammer, I could not get the cocking pin out of the hammer. It is an EXTREMELY tight press fit, and I could not get it to budge. This is very different from when I opened up my P-Rod, as the pin just came out when I pulled on it. I would really like to get this mod done - does anyone have any bright ideas for getting that cocking pin out?
Thanks,
Chris

You can probably get the o-rings in by removing the gripframe and manipulating them in through the sear opening in the tube.
